We do not support Motorola devices at the moment but we already have a feature request for that and I added this post to it.
With today´s TeamViewer release we now provide remote control for Motorola devices.
This feature is available for all new Motorola devices (e.g. Moto Z2 Play, Moto E (Plus) 4th Gen) and all devices that get an update to Android 7.1.1.
Users will be asked to grant a special access after installing our Android Host/QuickSupport app.
Enjoy the new feature!
